Lighthouse score stuck at 60-70 and the client wants 90+.

90+ in Lighthouse needs three things: little JavaScript, fast TTFB and optimised images. We usually hit 90 by fixing the top five items, not 100 small tweaks.

Try this first

  1. 1Run Lighthouse in incognito with cache off, mobile preset. Ignore desktop scores; Google ranks on mobile.
  2. 2Tackle 'Reduce unused JavaScript' first. Disable page-builder features you don't use, or drop the builder for a custom theme.
  3. 3TTFB under 200ms usually needs page caching (WP Rocket, LiteSpeed Cache, Cloudflare APO) and a good host. Shared hosting under 200ms is rare.
  4. 4Inline critical CSS and defer the rest. WP Rocket and most caching plugins do this automatically.
  5. 5Drop superfluous fonts. Three Google Font families is usually two too many. One, self-hosted, helps LCP.
  6. 6Re-test, screenshot the result, keep the evidence. Lighthouse fluctuates, average three runs.

When to bring us in

Can't hit 90 on a builder-heavy site? A rebuild on a leaner theme (Kadence, GeneratePress, Astra) or headless is the honest route. Bring in a performance engineer.
